Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,3-dichlorophenyl)propanoic acid (CAS 511272-38-1), a certified reference material (molecular formula C24H19Cl2NO4, MW 456.32 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(2,3-dichlorophenyl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 456.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
